Publication number: 20170063466Abstract: An amplitude encoded transmission system and method are disclosed that achieve an improved bit-error rate for systems with a non-linear input/output relationship in the presence of noise. A set of measures are determined for adjacent signal levels. The set of measures are compared to each other. When at least one of the set of respective measures does not approximate the remaining measures in the set of measures, one or more signal levels are adjusted until the set of respective measures of the transmitter approximate each other. The method can be applied during a select manufacturing stage of the transmitter. An integrated system includes an optical emitter, modulator, photosensitive diode and signal-level adjuster. The modulator receives a set of control signals to operate the emitter at a desired output level. The photosensitive diode generates a feedback signal that is used by the signal-level adjuster to generate a bias signal.Type: ApplicationFiled: September 1, 2015Publication date: March 2, 2017Inventors: Xiaozhong Wang, David Chak Wang Hui
